[PATCH] D102821: [SelectionDAG] Re-calculate scoped AA metadata when merging stores.

[Jeroen Dobbelaere via Phabricator via llvm-commits]

jeroen.dobbelaere added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:16736
 
+  Optional<MachineMemOperand::Flags> Flags;
+  AAMDNodes AAInfo;
----------------

(And move the merge logic to IR/Metadata.h)

Also note that I am not sure if it is safe to merge the TBAA part in this way. (Especially when using new struct path tbaa)
